Cold Air Intake for Lexus IS 250 350 (2005-2013) 2.5L 3.5L Engines

Sharpen Throttle Response and Induction Sound on Your Lexus IS GR Series V6

Who It’s For: Designed specifically for 2005-2013 Lexus IS 250 and IS 350 owners running the high-revving Toyota GR Series V6 engine family.

The Problem: The GR Series V6 is a sophisticated, high-compression power plant, but Lexus engineers prioritized cabin silence over airflow. The factory intake utilizes restrictive pleated paper filters and baffled plastic accordion tubing that creates massive air turbulence and heat soak. This design muffles the engine’s natural tone and creates a "lazy" throttle feel when you’re trying to merge or exit a corner.

The Solution: We engineered this kit to replace the factory clutter with a mandrel-bent T304 aluminum induction pipe. By providing a smooth, high-velocity path for oxygen to reach the throttle body, this kit corrects the factory design flaws of the GR Series V6, delivering reliable performance and a much-needed mechanical growl under load.

Why This is the Ultimate Upgrade

• Optimized Power Delivery: Real-world gains of up to 10% in horsepower and torque by reducing atmospheric resistance at the intake.
• T304 Lightweight Aluminum: Unlike cheap plastic, our mandrel-bent red aluminum piping dissipates heat faster and won’t crack or degrade over thousands of heat cycles.
• Zero-Mod Installation: This is a true bolt-on kit that integrates with your stock manifold system. It can be installed in under 60 minutes with basic hand tools and won’t void your vehicle warranty.

The Performance Promise

Buy with confidence. As specialists in the GR engine platform, we know that air volume is the key to unlocking response. Pro-tip: Always disconnect your battery terminal during the install for at least 10 minutes; this forces the ECU to reset its fuel maps and "learn" the new, increased airflow immediately.
